Epsom Salt - Magnesium Sulfate Heptahydrate Reviews

Breaks down in water very well.

Much better than the epsom salt I had from the hardware store haha

Good way to get extra magnesium

I know this is something you can get almost anywhere but I prefer to buy it from my friends I trust at BuildASoil.

Noticed an almost immediate difference

Perfect to water in for a quick Hit of Mag!!

Works great as a foliar spray. Dissolves fast.

Perfect for making your own CalMag w/o worrying about about adding synthetics. I add 1/4 tsp per gallon + 1 tsp of Demeter’s Destiny (Nectar for the Gods)!!

Corrected my magnesium issue in a week

Combined with Gypsum replaces any calmag solution

Use as directed. Love this company.

Suffered several magnesium deficiencies and used this to treat, very effective! I recommend to anyone who used potting mix 3.0 to pre-amend their soil with some of this stuff!

Clean product, arrived in a completely destroyed state missing shit half the purchased weight thanks to UPS mishandling it and buildasoil with the rockstar crew sent me out another as replacement. Amazing customer service, as always!! Thanks! Plants seem to really benefit from the addition of this and oyster shell flour in place of cal mag.

I use this in my living soil mix and as a top dress. Amazing product!

Highest quality epsom salts ive ever seen!

Not all salts are bad kids. Not for your margarita.

After being on the fence about the many places to grab my ingredients from I am very happy that I went with buildasoil. Hands down the best place with tons of info.

Second part to my organic CalMag. Great quality, as always!

I added this and some oyster shell flour to a tea and my plants really seemed to like it.
